Hi,

I wanted to know if there is a way of colouring my structure by bfactor, but with an additional condition where all bfactor==0 atoms are coloured in grey.

Currently, I am using a white to red gradient for my B-factors:

color bfactor range -2.2, 2.2

In this case, bfactor==0 values are coloured white. However, I would like them to be grey and outside the gradient (as they represent an unmapped portion of the protein).

Thanks!
